Painful Post-Operative Hip Study

The goal of this clinical trial is to learn if the hips of people who undergo revision hip arthroscopy look different from the hips of people whose hip pain is resolved with the first hip arthroscopy and of people who choose the steroid injection for pain management. Participants will complete one PET/MRI scan.

Hip arthroscopy utilization has increased significantly and, as such, people are now dealing with an increase in hip arthroscopy failures. In many cases, a failed hip arthroscopy is treated with a revision hip arthroscopy versus conversion to a total hip replacement, but these procedures may not adequately address the etiology of hip pain in the setting of a failed hip arthroscopy. Physicians need better diagnostic tools to appropriately diagnose post- hip arthroscopy hip pain, so that they can offer the appropriate treatment. The advent of FDG PET/MRI offers a highly sensitive imaging method that detects areas of abnormal inflammation. The sensitivity of this method exceeds that of other imaging modalities (e.g., MRI alone) and gives physicians the best possible chance of detecting abnormal inflammatory or hypermetabolic pathology. The ability to better diagnose pain sources around the articular joint with this unique approach has not yet been explored in the post-arthroscopic hip.
